The ending "-end" on dividend means "what something is going to be done to," so "dividend" means "the number being divided." The ending "-or," like "-er" in English, means "who is doing something," so "divisor" means "divider," "the number it is being divided BY." When you divide 63 by 9, 63 is being _divided_ (the dividend), and 9 is doing the dividing (the divisor). When we write it this way, usually using the "bar-and-two-dots" division symbol (called an obelus) 63 / 9 = 7 the number on the left is the dividend; it's being divided BY the second number. When we do the calculation like this ___7_ 9 ) 63 the number inside is the dividend. I once explained to a student that the 63 is lying on the operating table, and the 9 is the doctor standing next to the table operating on it. So the dividend is being divided by the divisor. (And the quotient is the organ he's just removed?) Maybe that picture can help. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/
